It's fun to think about different ways to play chess. Point- and deck-build systems are pretty interesting. I also like explosion mechanics, like your for example you could say that any one piece can keep moving (or move up to N times) as long as it keeps capturing. Similar to exploding dice, where after rolling 6 on a d6 you can roll again and add to your total, rerolling as long as you roll 6 again. Another one that could be interesting is a motivational or morale advantage, where let's say that if you capture an opponent's piece, another one of your pieces gets a free move (due to high morale on your side). I'll also confess that I enjoy turning chess into a dice-based war game at times :-) Nice idea for a post.
